MMAjunkie.com (www.mmajunkie.com) previously reported the three matchups, which are now signed and official.

WEC 53 takes place at Jobing.com Arena in Glendale, Ariz., and features a lightweight title bout between current champion Ben Henderson and challenger Anthoney Pettis. Bantamweight champ Dominick Cruz also meets Scott Jorgensen.

Zhang made his promotional debut at WEC 51 and took on short-notice replacement Pablo Garza, who stepped in for Jason Reinhardt. The Chinese national dominated the fight and finished Garza off with a first-round guillotine. “The Mongolian Wolf” now has finished 11 of his 12 opponents in the first round.

Downes took a big leap in his promotional debut when he stepped in for an injured Ed Ratcliff to meet veteran Chris Horodecki at WEC 49. Although he kept the Canadian at bay for two rounds, he suffered a submission loss via rear-naked choke in the second round. It was Downes’ first professional setback after stopping five of his six opponents viaTKO.

Wineland, meanwhile, looks for his fourth straight WEC victory following decision wins over Manny Tapia and George Roop and a TKO victory over Will Campuzano at WEC 49. The WEC’s first-ever 135-pound champ looks to reclaim his belt, which he lost to Chase Beebe in 2006. Wineland, who’s resurrected his career in the past couple years, is 5-1 since that title loss.

Stone, an American Top Team fighter who’s competed all over the East Coast, is a finisher who’s posted stoppages in all nine of his career victories. His only loss came via split decision to Jason McLean back in 2009 in a fight in which he broke his foot. Stone hasn’t exactly faced world-beaters thus far in his career, but the former NCAA Division III wrestler does own wins over Chris Simmons (6-0 at the time) and Ben Manseau (5-1).

Finally, Alcantara, a lightweight champion in longstanding Brazilian promotion Jungle Fight, makes his big-show debut after terrorizing the regional circuit in his home country. A member of the Pattaya Fight team, he enjoys a 10-fight win streak, though the WEC marks a step up in his competition level.

Lamas is on a roll in the WEC with three consecutive wins over the likes of James Krause, Bendy Casimir and Dave Jansen. The Chicagoan works with Top Notch Fitness alongside UFC veteran Gideon Ray and carries only one blemish on his resume, a second-round TKO loss to Danny Castillo at WEC 42.
